well to be honest these would be my first hifi cans other than some 10$ chinese headphones. I really don't know how the bass is supposed to be on closed or opened back headphones. i just hope it is enough for me cuz i am coming from kinda bassy IEM's.

I would really love to hear what you think about them!!!!

I am currently considering whether I should make the jump to a more useful portable V-Moda M100 type headphones or a more-acclaimed home listening open headphones like the HE-400.

If you are coming from cheap $10 headphones, you don't actually need to jump that much higher in price to get a big upgrade. I think going up to $100-200 you will already notice an improvement. Glad to see that you have sucha baller budged & I would love to hear your new-comer impressions of high-end equipment and whether it's worth the jump.
